Yes, the ESC you chose is a brushed ESC. Either GWS or an old Castle Creations Pixie 20P are about the only brushed ESCs you'll find anymore.
The main difference between a brushed ESC and brushless is that a brushed ESC only has 2 wires to the motor instead of 3.
If you click on the Tech Notes, you'll see all the specs on that ESC. It can handle up to 3S lipo, but you will need to make sure the motor can handle the volts. Most of the larger brushed motors (like a 480 or bigger) can handle 3S for a while, but it will burn out eventually.
Is there any chance you can switch out the brushed motor for a brushless? Eventually the brushed motor will die, and you'd have to replace it anyway.

I may be getting Older, But I Refuse to grow Up I am Having to much Fun to Grow Up LOL
I'm gonna have to change connectors on the motor and/or ESC anyways. I'll prolly go with small bullet connectors (or wire nuts.)
solder those bullets , wire nuts will be trouble, a two-cell 30-c will give MORE than enough power and everything will last longer, You ESC may not have a low volt cut-off for lipos, (though some do) so use a timer (6-10 mins) and check voltage, use 5-gram servos to keep the poundage down,bubsteve

Thanks. I always run a timer ... although sometimes I forget to start it. Or start it, think I forgot, and then stop it while trying to start it. Or accidentally set it to 'up' rather than 'down.' Or ...
All I have are 3S lipos, except for some tiny little ones. A quick test fit/jam of a 1300mAh 3S against the firewall balances pretty close. I'm currently disinclined to buy new batteries just for this plane.
And, with a brushed ESC, the voltage going to the motor varies with the throttle, correct? So I can reduce wear and tear by just going easy on the gas, correct?
Anyone ever use the GWS 15A brushed ESC? It comes with a heat sink and what appears to be a super-thin sheet of rubber, the exact size of the heat sink. Any idea what the rubber sheet is? Is there adhesive hidden in there or something?
